CHANNEL-FLAP-LAYING MACHINE.

Application filed December 14, 1922. Serial No. 606,909.

To all whom it may concern:

Be it known that I, IVILLIAM C. MEYER, a citizen of the United States,residing at Beverly, in the county of Essex and State ofMassachusetts,have invented certain Improvements in Channel-Flap-LayingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to devices for laying the channel flaps of thesoles of shoes and is illustrated as embodied in a well known t ,e ofmachine emolo in an any i b nular flap laying tool arranged to berotated by a power driven shaft.

In operating machines of this type, it is customary for the operator todo all his work on one side of the machine and it is desirable thatprotection be provided for the other side of the annular tool to preventunintentional engagement with the shoes or with the operator. to work onthe right side of the machine and some prefer the left and, accordingly,it is also desirable that the tool be protected in such a manner thateither side may be left unobstructed for use.

The present invention contemplates the improvement of channel flaplaying ma chines of this type by providing a guard member in combinationwith the annular tool, the guard member being so constructed and soarranged with reference to the tool as to protect one side of the toolwhile leaving the other side unobstructed to facilitatethe presentationof the work. In a preferred form the guard is arranged to be reversedfrom one side of the tool to the other according to the preference ofthe operator. In the embodiment shown in the accompanying drawings astandard is provided which carries a rotary shaft on which the tool ismounted and this standard has symmetrically disposed positioning partson opposite sides of the shaft arranged to engage corresponding parts ona guard-carr ying clamp member so as to determine respectively right andleft positions of the guard in mirror relation to each other.

The above and other features of the invention including specificconstructions of parts and various novel combinations will Someoperators prefer be apparent from the following description of anillustrative embodiment of my invention shown in the accompanyingdrawings in which Figure l is a perspective view, partly broken away,showing the top part of a flap laying machine; and

Fig. 2 is a front elevation of the guard, the tool being removed and theshaft shown in section to illustrate more clearly the alternativepositions of the guard.

The illustrative machine comprises generally a standard 10 formed withbearings 12 and 14 for a rotary shaft 16 driven from any suitable sourceof power by a belt engaging a pulley 18. The shaft is arranged to have aslight longitudinal play in the bearings, its movement being limited byengagement of the hub of the pulley 18 with hearing 12. The shaft 16carries an annular flap laying tool 22 mounted on a dish shaped carrier24 secured on the front end of shaft 16. The tool and shaft are urgedinto forward position by a coil spring 26 engaging a collar 20 and thehub of carrier 24.

The tool 22 may take various forms according to the use for which it isintended, the particular form illustrated in the drawings being intendedfor use on Goodyear welt shoes. It is the intention that interchangeabletools 22 of different kinds be provided, and that a welt tool or a McKaytool or any other desired form of tool be secured to the carrier 24 for'use with the machine as above described.

In accordance with the present invention a guard 30 is arranged toprotect approximately 120 degrees of the periphery of the tool toprevent unintentional engagement with the work or with the operator. 7It will be observed that the guard does not interfere with the use ofthe machine as it leaves one side of the tool entirely unobstructed.

The guard 30 is securely attached to, or is integral with, arms 32carried by one member 34 of a clamp. Member 84 is approximatelysemi-cylindrical, and encircles one side of the bearing 14, its radialposition, and consequently the radial position of the tool itself, beingdetermined by engagement of one of its end surfaces 36 or 38 with ribs40 or ribs 42 of standard 10. The ribs 40, 42 and the cooperating endsurfaces 36, 38

are so relatively arranged as to locate the guard radially relatively tothe tool in such a position as notto interfere with the properpresentation of the work to the tool 22 by the operator. Clamp member 34is held in place by clamp screws 44 engaging co-oper-v atingclampmembers 46 and 48.

If the guard is to be on the left hand side of the machine, as shown inFig. 1, and in full lines in Fig. 2, .its position is determined byengagement of end surface 36 with ribs 40. If it is to be placed on theright handside of the machine as shown in dotted lines in Fig. 2, itsposition is determined by engagement of end surface 38 with ribs 42.Ribs 40 are of the same form as ribs 42, and ribs 40 and 42are arrangedsymmetrically on standard 10 with respect to the axis of shaft 16. Endsurfaces 36 andBS are arranged in such relation to guard 30 that whenthey engage ribs 40 or 42, as the case may be, they determine twopositions of guard 30 which, as-shown in Fig. 2, are in mirrorrelationto one another. 7

While one form of the invention has been illustrated and described, itis not my intention to limit its scope thereby or otherwise than by theterms of the appended claims.

Having thus described my invention, what I claim as new. and desire tosecure by Letters Patent of the United States is 1. A channel-flaplaying machine having a rotary annular flap-laying tool, a 'guardconstructed,andarranged to protect one side of the tool while leavingthe other side un obstructed, a standard upon which the tool I ismounted, a clamp for rigidly but removably securing the guard to thestandarchand cooperating portions on the clamp and standardfordetermining the al'ilCllELl position of theguard relatively to thetool.

2. A channel-flap laying machine having a rotary annular flap-laying.tool and a guard which is constructedand arranged to protect one sideof the tool While leaving the other side unobstructed and which isreversible from one side of the tool to the other.

'3. A channel-flap laying machine having, in combinatioma standard, anannular flaplaying tool mounted for rotation in the ,standard, and aguard constructed and arranged to protect one side .of the tool whileleaving the other side unobstructed, the

guard and standard being formed with two sets of positioning andengaging portions to determine respectively right and left positions ofthe guard in mirror relation to each other.

4. A channel flap-laying machine having, in combination, a standardhaving symmetrically disposed positioning parts on opposite sides, arotary shaft carried by the standard between said parts, an annularflap-laying tool secured to the shaft to be rotated thereby, aguardconstructed and ar ranged to protect one side of the tool whileleaving the other side unobstructed, and a clamp member carrying theguard and coir structed and arranged to be clamped to the standard andhaving positioning parts to be engaged alternatively with'either of thesymmetrically dispose-d parts of the stand ard to hold-the guardabout-either the right or the left side of the tool.

5. A channel flap laying machine having, in combination, a standardprovided with a bearing, a shaft journaled in said bearing, an annularflap laying tool secured to the shaft to be rotated thereby, a guardconstructed and arranged to protect a portion of the tool atone side ofthe axis of rota.- tion of the tool while leaving the tool. unobstructedat the opposite side of said axis, a member carrying the guard andadapted to encircle said bearing, means for detachably securing saidmember to the bearing, and a positioning portionon .the said .men

her for engaging with the standard to de termine the radial .positionofthe guard relatively to the tool.

I '6. ,A' reversibleguard'for a rotary tool journaled in a bearinghaving projecting portions symmetrically disposed with re-.

spect to the axis of the .tool comprising a member shaped to protect oneside of the tool while leaving the other side of the tool unobstructed,a clamp carried by said .mem-

berand adapted to encircle the bearing, and

position ing. surfaces symmetricall 1 arranged relatively to the axis ofthe clamp for .cooperation with the projecting ,portionsof the bearingto locate the tool protecting vmember in similar positions at oppositesides of the tool.

In testimony whereof I have signed my name to this specification.
